How do you reset an I-tech to factory Defaults?

I inadvertantly screwed up and assigned a subnet mask of all 255's (255.255.255.255) and applied it. Now my I-tech won't list in IQ utility at all. What is worse is that all functionality is locked out on the front panel! I can't even use the amp at all since it won't even turn on!

How do I reset the amp to factory defaults? I've scoured the manual and this forum to no avail. Please don't tell me I have to open the amp up and pull a battery or something.. HELP!!
